This fine video from Audubon shows close-up views of the American Oystercatcher, and unleashes more of the distinctive call-sounds – an insistent wittering – of the species. [vimeo https://vimeo.com/48479131%5D

For some time, I found it difficult to distinguish American and Eurasian Oystercatchers. The markings of both species are variable according to gender, age, season and so on, but are generally very similar. Mrs RH noticed the salient difference at once – the eyes. The AMOY has bright orange eyes with red eye-rings; the EUROY’s eyes are the reverse colouring, as this example shows.
